EXHAUST HEAD F OR EXHAUST-STEAM PIPES.

Application filed June 10, 1922. Serial No. 567,477.

To all whom it may concern:

Be it known that I, ARTHUR J. FILKINS, a citizen of the United States,residing at Riverside, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Exhaust Heads forExhaust-Steam Pipes, of which the following is a specification.

As is well known, exhaust steam pipes for exhausting the-steam fromengines and the like, when installed in cities or other closely builtlocalities, are commonly carried upwardly to a point above the roof ofthe building in which the steam engine is located, and

r from this point the exhaust steam is expelled with considerable forceinto the atmosphere in a series of sharp staccato puffs in rapidsuccession. This results in a spray of minute particles or drops ofwater accompanied frequently with small globules of lubricant, as oiland the like, being discharged into the atmosphere with the steam, whichhas the objection of wetting and soiling anything'within its path ofdescent to the street level.

This discharge of steam from steam exhaust pipes has proven such anuisance that cities have found it necessary to pass ordinancesprohibiting the discharge of exhaust steam pipes into the atmosphere,unless such pipes are equipped with a suitable trap or exhaust head formuflling and controlling the discharge therefrom.

The primary object of. the inventionis to.

provide an improved exhaust head which will so control the exhaust steamas to check the force and mufiie or deaden thesound with which thesteamis expelled into the atmos phere and cause the steam to rise fromthe exhaust head in a gradual manner and without force.

A further object of the invention is to provide an exhaust head thatwill expedite condensation and collect all condensation of steamtherewithin and direct the water re-. sulting therefrom to a roofgutter, sewer or other point of discharge.

Other objects of the invention will appear from the followingdescription of the preferred form thereof, shown also in the drawingforming a part of the specification, the features of novelty being setforth in the appended claims.

In the said drawing, Fig. 1 is an elevation view, partly in section, ofthe improved exr Reference character 10 indicates the outer i casing ofthe improved exhaust head andhas the nterlorly screw threaded portion 11extending downwardly from the bottom thereof for receiving exhaust steampipe 12 in screw threaded engagement therewith, as at 13. gcrew threadedportion 11 extends upwardly lnto the casing 10 forming an annular wall14 around the central internally screw threaded opening 15 in'the bottomof casing 10, thus forming a gutter or drainway 16,'which communicateswithdrain pipe 17, which has screw threaded engagement with the screwthreaded opening 18 adjacent the drainway 16. Drain pipe 17 maycommunicate with a roof gutter, sewer or any other means for thedisposal of waste water and is forth'e purpose of draining water whichis collected in utter 16 from the condensation of steam wit in theexhaust head. The wall of the outer casing 10 is thickened at its upperend, as at 19, and isrecessed on its inner periphery forming a seat 20for the reception therein of radial arms 21 on the circularcup likebafile 22. Baflle 22 is suspended within and concentrically with outercasing 10 with its wall spaced from the wall of the outer casing toprovide a passageway for the exhaust steam upwardly to cap23. Cap 23 isformed With an inwardly extending wall which is inclinedtowardthecenter, first upwardly as at 2 1, and then downwardly, as at 25, formingan apex 26. The downwardly inclined wall 25 terminates in a downwardlyextending portion or throat 27 which extends into and concentricallywith the vertical wall of baffle 22. The cap 23 with its, downward lyextending throat 27 thus forms a second and abrupt battle in the path ofthe exhaust steam which practically completely checks the force withwhich the steam is expelled from the outlet of the steam head. The steamis thus caused to rise from the steam head in an approximately uniformflow and with greatly reduced force. Baffle 22 has a concavo-convexbottom 28 and is provided with an outlet 29 for water collecting in thebaflie from the condensation of steam which outlet discharges into theouter casing 10, and from which the water thus collected is carried fromthe outer casing by pipe 17 to a point of discharge.

Casing 10 has radially'extendingears 30, preferably three in numbr,which ears are bored, the bores being adapted to register with similarbores through. ears 31 carried by cap 23 for the reception therethroughof bolts 82 which are adapted to receive thereon screw threaded nuts 33for securing the assembled parts of the exhaust head in proper relation.

It will be appreciated from the foregoing disclosure that exhauststeamexpelled into the exhaust steam pipe from the cylinder of an engine willfirst come into contact with the bottoin28 of baffle 22 and be given adownward and outward course, and will pass thence upwardly between theouter wall of the battle cup and the wall of casing 10 into contact withthe top cap 23, being thence deflected downwardly aroundthe outerperiphery of throat piece 27 and thence upwardly and outwardly throughthe discharge opening therein, thus greatly reducing the force andrapidity with which the exhaust steam leaves the cylinder head. At thesame time particles of oil or condensed steam will be entrapped anddrained through the drain pipe 17.

In order that the invention might be understood I have shown the detailsof the embodiment of the invention that has been found most successfuland that is preferred by me. but it is not desired to be limited to thedetails of the invention except as defined in-the claims, since it willbe apparent that persons skilled in the art may resort to variousmodifications without departing from the purpose and spirit of myinvention.
